The reel ot paper board l. see Fig. l. is mounted on a collar loosely mounted on the shaft 3, said collar beine` fixed lo the lateral, oppositeljv disposed spiders l. l'o:` side-guiding the reel of' paper board l. The brake shoe 5 engages the collar (i. integral with the core 2, said shoe 5 being mounted on the arm 'T oi the hell crank S. pivotod at 9 on the bracket 10. The arm l1 of the bell crank S is tensioned b v the coiled spring 12, adjust-ed in tension by means ot the threaded rod 13 and the nut 14.

.Upon rotation. of the. power shaft 94, the lever 88, and therewith, the shaft 89 and the respective lever 87, see Figs. land 8 are oslugs 82 and 83 'are brought into engagement,- whe-reby uponl further forward oscillation of the levers 88, 87, the carriage 81 iscausedto slide forwardly on the slides 95, 962 The slides v95 and 96 are supported on thebars 97, 98, which latter serve also to tie the frames 17 and 18 together. rlhe extent of' forward movement of the clamping memloer .72 is indicatedin Fig. 10 and also in Fig. r1, by full 'and dotted lines,`showing respectively the initial and filial positions. Thev carriage 81,( and' therewith the lower clamping member 7 3, move forwardly to the ysame extent as the toe 72, the paper board and'rv 'finish paper 59' being clamped and positively held between the clamping members 72, 73, during such forward or feeding movement.A lf'tfwifll'fbe noted that the arrangement vprovided for, as just described, attains selfaccommodation of the clamping members 72, 73, todifferent thicknesses of paper board or finish paper, or both, and at the same time insures the clamping of the paper boardandfr finish' paper 59 b etween the toe 72 and the lower clamping member 73 at a predetermined instant prior to any movement ofthe carriage 81. vUpon the attainment of the carriage 81 to its final position forwardly, as indicatedby dotted lines in Iixigs;` 1, 9 and' 10, the paper board and finish paper 59 isclamped in such forward posi- Vtion and held by the clamping bar 99, prior to' severing of the paper board and finish paper the severing means 100. The clamping bar 99 extends across all thei strips of paper board and finish paper 59, forv the cover rim, neck and tray rim, respectively, and' ismounted at its opposite ends'onither posts 101, and povided with thecompression springs 102, adjusted by suitable nuts asshow-n.

The severing means 100' comprises three o separatelower fixed knifeedges and three corresponding upper, movable separate knives 103i. The upper knives 103 are mounted: on the yokev 104, mounted in the oppositey guide .blocks 105, fixed'to the front and rear frames 18, .17.

' The: oke 104 is pivotally mounted by the stu-s106, orthe links 107, suspended on" thefstuds 108, carried by the oscillating lever-S109, 110, respectively pinned to the shaftlll, mounted at its ends with suitable bearings carriedV byi` the rear and front t ,i y f v fra-mes 17, 18. The lever 110 is provided with the stud 112, to which is pivoted the operating fork 113.

Means are provided ior positivo cutting!` actuation of the knives 100. 1021 and for positively opening the severing means. and in the embodiment shown, the fork Y113 provided with the stud 1.14, on which is loosely mounted the upper roller 115, riding the external cani 116. The fork 113 is further provided with the lower stud 11.17, on which is loosely mounted the lower roller 11,8. rooperating with the cam 119.

The operating surfaces of the rams 11() and 119 are mounted on the power sha l't 111. The fork 113l is guided by the block 120. loosely mounted on the sha-ft 94, whereby the wear is distributed over a. relatively largo surface .zontact, and in the event of undue wea-r, renewal of the block 120 alone is requi-red.

The strip of paper board and finish paper. after being severed to the desired length or lengths by the aforesaid severiner means 100, 103, and now designated 121, is passed onto the table 121, between the opposite side guides 122 and the upper guide 12?). '.Ihil side guides 122 are preferably beveled inwardly as indicated in plan view in Fig. 2, and are respectively of similar construction of inward bevel as the side guides 70, as shown in Fig. 8.

The upper guide 123 is mounted on the block 124, clamped on the shaft 125. carried by and between the rear and front frames 17, 18. Such forward feeding of the severed strip 121 is effected by the rollers 120.

l127, respectively driven by the internleshing,r

gears 128, 129.

Upper feed roller 127 and its gear 129 are loosely mounted on `the stud '130. carried by the lever 131, supported on the shaft 13:2r and is arranged for positive li lftinpv action manually, similar to the aforesaid sets of drop rollers 32, 43 and (i8. 69. The upper roller shaft 132 is operated by the lever l2-i3, provided with the stud 134, on which is pivotally mounted the fork 135, ha vi ng the stud 136, in which is loosely mounted the roller 137 (see Figs. 1, 2, 4 and 14) cooperating With the cam 138, mounted on the power shaft 94. The roller 137 is held in coac't'ing relation to cam 138 by the spring 139, having its one end attached to the lever '140, fixed to the upper roller shaft 132, and its other end attached to the rear frame 17. The lower roller shaft 141 is positively driven by the sprocket 1,42, meshinpY with the chain 143, driven by the sprocket 144, fixed on the shaft 145, journaled through the front fra-me .18, vto which is fixed the pinion 146, meshing with the drive gear 14T. fixed on the power shaft 94.

The fork 135, at proper timing of its cam 138, raises the upper drop roller 127, to re- "-Tliefrwespective parts of the vmntinuous JEeed and --eilttmg kmechanism are mounted `on the indi'cateffl shafts Journalled in Ithe rear and front 'frames 1T, 18. "The anterior 4feed rollers" 176, 177 are intergeared, similarly the cutting cylinders 178, 180 {l1-nd similarly the 'positioniieed rollers l'S, i852. Thesha-ts ofthe loiver ieec'l'fro'llers 177, l182 and the l'lower l'cutting cylinder 180 are 'directly driven by gearingconne'cting with' the -,o\ver shattffll, as ivill be understood. lire e'rab'ly the adhesive fountain QS provides -adhesive in `conollnm 'to' the three applyling rolls Q9, whereby substantially "the me, oruniilo'rm consisten-ry yoi' adhesive is suppliedtofthe respective tray rim, neck and coverrim "partsfor' the res'pertive boxes, Vas Vinvaccordance with the principle above stated, or forming the 1parts of any box jat substantially the same time, i.
